INVENTOR ATTORNEY 1a; c'itiz en of the Unitedl'States,fresiding at; Charlesftom-lin' l'thei'fcoiint'yl of Kanawha and State of West Virginia,have invented new and" useful" Improvements in Truss-Form;

Patented Q E S,

Systems, ofwhich tl'le ifOllQWlllg is aspect .means at one end of. thebeam 9.

This inventionrelates truss formffor use in supportingceilings,floors'and the like in steel frame buildings, the general obj ect of theinvention being to provide means whereby the forms can be easily andqulckly setup, the material used over and over again'andaj clear floorspace left ;i'orfthe workmen when the trussis infpositionfto support aconcrete mold' or'forrstorage of material 7 V This invention otherfeatures of construction" and in; the combination and arrangement of theseveral" parts, to be hereinafter fully described, il-

lustrated in the accompanying drawings and specifically pointed out inthe appended;

claims. it Y In describing-.my invention indetail,

reference willbe hadto the accompanying drawings wherein like charactersdenote like 7 or corresponding! parts throughout the] several views, andin Wh c1 a Figure 1v is a sectional view showing the inventioninusa. I 17 Figure 2 is a section'fon line 2-2 of Fig re 1. a r Figure 3 is asectional detailviewof the Figure, 4 is a' of the hangers. I Figure 5 isarview of the means for connecting the cable 15 to the bolt 17.

Figure 6 is a sectional view showing a modification.

perspective view ofone Figure? is a perspective: view of one end of thebeam 9 shown in this modification.

As shown in these views, I provide hangers 1 forengagingthe Ibeams 2 ofthe building, these hangers having hooked ends 3 which form spaces oftapered formation so as to engage the flanges of the I beam and bymaking them taperedfthe hangerscan be used ondifl'erent sizes of Ibeams. They are provided with bolt holes 4 so that they can beheldin'placewhile the system is being .erected'and they are also rovidedwith'the large. holes 5 for,receiv-.

plates 8 I I plates are each provided with a hole-12 for receiving themember 13 of. the turn-buckle device 14 to whieh'thecablel5fisf-cflonneotedg A- steel frame 16, preferablyfonned of angle iron,is'fa'stenedlat' its upper end to the beam 9' and the cable passesoverthis frame I and. is looped-- through the eye in a bolt' 17 and then hasits end clamped to another part ot-the ,cable by the"'clamp 18f so thatthe v length fofQthecable can be' adjusted.f The bolt 17 engages a plate'8 at the opposite'e'nd ,ofthebeam 9 which is similar to the platehanger which is the same as that shown at'l V, or "where thejsystem isused in continuous 5 bays, the hangers between" the bays are lformedasshown at 1 with each extremity bent upwardlyand provided with ra pairof holes 5 .for receiving the bolts 6. These "8. This end of the beamcan be attachedtoa I hangers can be fastened tolthe, I beams by.

the clamps 19'.

Where short spans are being constructed, 1'

the system shown in Figure '6 and 7 may be E -j used." In. this caseplates 2O are placed in notches formed in the ends of the beams 9forreceiving the bolts 6 instead of the angle 7 plates shown at'8 in:the first form of theinvention and this system alsoomits'the:

- 'This, system not only takes the place of shores but it will carry aheavier load than thesystem'using shores and can be quickly erected.-Itiwill also give "aclear floorspace below and the cost oferecting isonly-half as much [as-the shore system andv requires one-third lesslumber.

It isthought frornthe foregoing desorip- 1 tion that the r-advantagesand novel features of my invention willbe readily apparent.

I desire it to be understood thatflI may make changes in theconstruction andin the 'combination'an'd arrangement of the several 1parts, provided that such changes'fall with- 1n the scope of theappended claims. I I

What I claim is i 1. A truss system comprising hangers for engaging Ibeams of a building, some of the no hangers having hooks thereon forengaging the I beams and each'hanger havmg a plurality" of holestherein, bolts pass ng through certain of the holes in the hangers,

nuts for holding the bolts in the hangers,

a beam and plates at the ends of the same having holes therein throughwhich the bolts pass and truss means for the beam, such means consistingof a frame connected with the beam, a cable passing over the frame,members passing through holes in the plates at the ends'of the beam, aturnbuckle arrangement connected with one memher and to which one end ofthe cable is connected and clamping means for adjustablyconnecting theother end of the cable with the other member after the cable has beenpassed through an eye in said last men- 25 tioned member.

In testimony whereof I aflix my signature.
